SAP HANA

I have few queries regarding SAP HANA i would like to get into HANA, before that i am a Post graduate in Management education and having little bit of technical skills,
Here my question is,
what is SAP HANA, to learn it whether the person should first of all go through ABAP, with which module the HANA is integrated,
whether it is technical job, or integration, or application maintenance, because i have a knowledge of SAP HCM module too.

Really appreciate the experts who can clarify my queries in all respect.

Yes, HANA is hot right now. I understand the desire to jump on the hot new thing, but you have to do some homework and some serious skills self evaluation first. Please review ALL of the links Waza provided. They should be very helpful to you.

HANA is very technical. It can run beside your ERP and/or BW system at first (all modules), but eventually it can replace the database entirely. As such, you should pursue technical skills like database administration or system administration to give you the foundation necessary for a career implementing HANA. HANA does not have programming (ABAP) as a primary skillset. Unfortunately, neither your postgraduate work in Management nor your experience with SAP HCM will help you. I'm sorry to break it to you, but HANA implementation may not be in your future. Concentrate on the skills you do have and you'll do fine.

To jump in the new world of HANA is enticing idea. But no company will trust a newbee with their mission critical, latest, greatest and CEO busting technology. To be considered you would need a long history of Unix/linux and or x86 WinTel technology administration. Think of it as trying to be a BASIS administrator.

Of course to justify your position you have to prove a 10 fold leap in performance as measured by number of transactions. I am not saying it is impossible, but. Think of it this way, as a SAP HCM manager of many years experience, what would you look for in a SAP Basis Admin deploying HANA?

There are a lot of us wo ant to be HANA deployment people, but we are just not qualified.
